Shirai Group

What Shirai Group does

Shirai Group (白井グループ株式会社) is a family-owned Tokyo-headquartered environmental services group tracing its origins to 1933 and operating under the current holding structure since 2003. The group provides end-to-end waste management to business operators, building owners, and government entities across Tokyo's 23 wards and the wider Kanto region. Core revenue lines are: scheduled commercial waste collection (combustible, non-combustible, paper); one-time bulky waste and special waste collection (PCB, asbestos, electronics); confidential document and media destruction under the proprietary SS-Security-BOX service; plastic recycling at the Tokyo Material Recycling Center (東京MRC) opened 2024; and complementary building maintenance services. Subsidiary Shirai Transport maintains long-term contracts with Tokyo metropolitan wards for household waste collection, and the group holds general and industrial waste collection permits across all 23 Tokyo wards — a regulatory footprint that is difficult to replicate.

The group's commercial offering rests on three differentiating technology assets: (1) the SS-Security-BOX system with GPS satellite monitoring, image documentation, and online transport completion certificates for confidential material handling; (2) electronic manifest support via the national JWNET system, replacing paper 7-copy manifests with digital tracking; and (3) the ごみ.Tokyo web-based booking platform with QR-coded vehicles that enables online scheduling for commercial collections. Recycling processing capability at Tokyo MRC supports horizontal recycling of stretch film, pallets, and clothing cases; consumer-grade outputs include Eco-Mark-certified 100% recycled plastic garbage bags. Operational innovations (easy-lift vacuum balancers, muscle suits, heat-resistant pavement reducing surface temperatures by ~9°C) mitigate labor intensity in a workforce-intensive business.

Commercially, Shirai Group runs a transaction-fee / professional-services pricing model with customized monthly contracts for regular collection, per-service fees (including a ¥1,000 manifest fee for spot/bulky waste), and customized building maintenance scopes. Distribution is sales-led, combining direct phone and website inquiry handling, a referral network of property managers and cleaning companies, and government tender contracts. Disclosed revenue is ¥2.6 billion with 239 employees and 101 vehicles. The customer base spans offices, retail, restaurants, schools, festivals, real estate operators, and corporate sustainability programs (Suntory, Nomura Real Estate, Ascal). Family ownership, ~90 years of operating history, Eco-First certification, and ESJ AWARD recognition form the reputational backbone of the business.
